COLEOPTERA. 61 



has favored me with specimens in all their forms. This insect 

 is now known to inhabit nearly all the States i}i the Union. 

 I am inclined to think that the Brenthians onght to be placed 

 at the end of the weevil tribe ; but I have not ventured to alter 

 the arrangement generally adopted. 



The rest of the weevils are short and thick beetles, differing 

 from all the preceding in their antennje, which are bent or 

 elbowed near the middle, the first joint being much longer than 

 the rest. Then- feelers are not perceptible. They belong to 

 the family Curculionid.e, so called from the principal genus 

 CurcuUo, a name given by the Romans to the corn-weevil. 

 The Curculionians vary in the form, length, and direction of 

 their snouts. Those belonging to the old genus Oiircidio have 

 short and thick snouts, at the extremity of which, and near to 

 the sides of the mouth, the antennce are implanted; those to 

 which the name of Rynchcems was formerly applied have 

 longer and more slender snouts, usually bearing the antennas 

 on or just behind the middle ; and the thkd great genus, called 

 Calandra, contains long-snouted beetles, whose antennae are 

 fixed just before the eyes at the base of the snout. 



CurcuUo {Pandeleteivs) hilaris of Herbst, which we may call 

 the gray-sided Curculio, is a little pale brown beetle, variegated 

 with gray upon the sides. Its snout is short, broad, and slightly 

 fmTOwed in the middle ; there are three blackish stripes on the 

 thorax, between which are two of a light gray color ; the wing- 

 covers have a broad stripe of light gray on the outer side, edged 

 within by a slender blackish line, and sending two short oblique 

 branches almost across each wing-cover; and the fore-legs are 

 much larger than the others. The length of this beetle varies 

 from one eighth to one fifth of an inch. The larva lives in 

 the trunks of the white oak, on which the beetles may be found 

 about the last of May and the beginning of June. 



The Pales weevil, CurcuUo {Hijlobius) Pales of Herbst, is a 

 beetle of a deep chestnut-brown color, having a line and a few 

 dots of a yellowish white color on the thorax, and many small 

 yellowish white spots sprinlded over the wing-covers. All the 

 thighs are toothed beneath, and the snout is slender, cylindrical, 

 inclined, and nearly as long as the thorax. On account of the
